Good Additives

[driversdomainuk 8]

Hi

 

I finally got myself a decent 20ltr stainless steel jerry can from Demon Tweeks at the weekend - saves having to attend hillclimbs with two diesel plastic containers!!

 

Anyway, I am now running a 2 gallon fuel tank in the back of the car and so can fill up knowing there is no gunk or crap sat at the bottom of a 20 yr old fuel tank.

 

I mostly use Shell V Power, but when out of season just normal supermarket stuff. As I hardly use the car now on the road I might as well use V Power all the time....I will of course be filling up my new jerry can with this stuff and will keep it topped up as a supply....quite good actually as 20ltrs should do a weekend of hillclimbing without visiting the petrol station...

 

Now I need to know peoples view on fuel adsitives....I am not running increased CR and so I dount octane booster will do much....???

 

Is there any fuel additives, which would be useful for me, using V Power..? Its an M116 on weber carbs...no other mods to the engine...

 

I know lots of additives dont work, and so need to get the right stuff...

 

Cheers

Rob

any additive that's not an octane booster would be rather pointless.

 

if you really want consistent results and be able to run more advance you'd need to run race fuel, some of which actually is available from the pumps in selected filling stations, but otherwise in drums.

Just buy fresh petrol regularly. V Power has a shelf life of only two weeks, before the good stuff goes off and it reverts to 95/96. Caltex 98 seems to be a lot more stable and consistent (if you have that in the UK).

Not really...there are value lubricants etc..I am not neces looking for more power, just something good for the engine...if that releases more power - great. If it does not add power, but helps keep the engine in good condition, thats fine also...

 

sorry I shoul dhave said that at the start!

I might as well get standard Shell and add an octane booster in - less likely to "go off" as with V Power....?

If you wish , try "Xylene" or "Toluene" , i did and it works ... but the effect might depend on how much this stuff is already premixed in the petrol from refinery .. or if they used some other chemical to boost up the octane rating , such as MTBE ..

 

Premixed octane boosters which can be bought in the stores are ,in my opinion, waist of time and money , cos they don't really do much if anything al all .. at least the ones which i've tried ..

V power goes off in two weeks

 

Seems pointless in filling the tank once a month, if at all if the petrol station has old stock still left in the station.

 

So if fuel boosters are a waste of time & money then what can you buy to keep a good octane level that is easily available ?

Fuel stations have a pretty high turnover, fuel going off in their tanks isn't an issue I would worry about.

Not to Piss on anyones chips but;

 

S10.5.1; For roadgoing series production, roadgoing specialist production, modified limited production, modified specialist production and hill climb super sportscars, pump fuel is mandatory. Only air may be mixed with the fuel as an oxidant.

I did think about mentioning this yesterday, but to be honest, if you pre-mix it in jerry cans and turn up at the event who would know?

 

The rules for testing fuel have been in place for years and they have made it mandatory for British or MSA Championship level cars to have fuel sampling connections, but in reality how much testing of fuel is ever going to happen due to the cost.

I've been marshalling/driving at sped events for about 28 years and have never known a competitor's fuel to be tested, but there is always a first time especially as you mention the dry brakes that have to be fitted.

I know our friend driversdomain and don't want to see him getting any problems because of this.

Is there any point? Don't mean to further piss all over the embers but you aren't going to benefit from running higher octane fuel unless you tweak the ignition to suit. You really want to go and have the ignition mapped with a tank full of the fuel you intend to run to see any benefits, otherwise you're just pointlessly burning expensive fancy fuel.
